Cancer is a disease in which abnormal cells grow, divide, and spread. In most cancers, these abnormal cells form a mass called a tumor. (Not all tumors are cancer.) Cancers found in the blood or immune system do not form tumors. Most cancers are named for where they start. For example, lung cancer starts in the lung, and breast cancer starts in the breast. But cancers can spread. They can invade nearby tissues and organs. Or, they can break away and spread to other parts of the body. Symptoms and treatment depend on the cancer type and how advanced it is.
Overall, cancer rates for Asian-Americans are lower than other groups. Yet, cancer is the leading cause of death in Asian-American women. The most common cancers found in Asian-American women include breast cancer, colorectal cancer, and lung cancer. Asian-Americans also have higher rates of some cancers that are caused mainly by infections. This includes stomach cancer and liver cancer. Among U.S. women, Laotian-, Samoan-, and Vietnamese-American women have the highest rates of cervical cancer, which also is caused by infection.
A number of factors can affect a woman's cancer risk. Some factors, such as getting older and family history, cannot be controlled. Yet, you can lower your risk of some cancers by changing some aspects of your life:
Women also can protect themselves from cancer by getting regular checkups and screenings. Screening tests can help find cancers such as breast cancer, cervical cancer, and colorectal cancer. This way, if cancer develops, it is likely to be found early. Treatment often works best when cancer is found early. A vaccine can protect women from infections that can cause cervical cancer.
Asian-American women are less likely to get regular cancer screenings than women in other groups. Not having health insurance, a regular doctor, or ability to pay are some reasons why Asian-Americans have lower screening rates. Some people don't understand the causes or risk factors for cancer or the benefits of screening.
We don't always know why one person develops cancer and another does not. Yet with a healthy lifestyle and routine screening, you will feel good knowing you are doing what you can to lower your cancer risk.
